Ben,

It's just the reverse, a cookie has an expiration date and CF will use the day value to do an implicit dateAdd w/ now() to compute it for you, since often times you don't care about the actual expiration date, just how far in the future it is. Here's a sample cookie string (for a domain-global cookie set to expire in 30 days):

EL_TOKEN=3AF281672CDBEE7C793805351DB32E11D4; Expires=Fri, 02-Jan-2009 17:07:09 GMT; Path=/

I don't know much about cookies outside of the CFCookie tag, so out of curiosity, do cookies really have an expiration date? Or is ColdFusion just taking that date and calculating the difference in days behind the scenes?

Using a date is really useful, but I was just wondering if it is some sort of short-hand for getting the day-difference?
